The South Korean domestic research team succeeded in discovering quantum mechanics material.
The Ministry of Science, Technology, Information and Telecommunications stated that a research team led by a Dongguk University professor managed to identify for the first time the phenomenon of new quantum matter arising when a ‘spinning cloud’, a characteristic of which appears at extremely low temperatures, is condensed.
A swirling cloud is a phenomenon that occurs when lowering the temperature of metallic and semiconductor materials, the electrons surrounding the impurities gather like clouds.
This phenomenon is exploited in magnetic levitation trains or Magnetic Resonance Imaging (MRI).
However, the existence of rotating clouds was demonstrated for the first time in 2020 although it was thought to have occurred in the 1930s due to limitations in experiments to provide very low temperature conditions.
The research team found through spectroscopy and electrical conductivity measurements that when the temperature of metallic silicon is lowered to a very low temperature close to absolute zero (OK, minus 273.15 °C) to create a rotating cloud condensing situation, the new material is in a “Bose-Einstein condensation” state. already made
A Bose-Einstein condensation is a state in which particles called ‘bosons’ condense with each other at extremely low temperatures and appear to be one object with quantum mechanical properties. It is also referred to as the fifth state which is different from solid, liquid, gas, and plasma.
A team of researchers working on quantum computing devices in 2015 confirmed that a new, never-before-seen signal appeared in metallic silicon mixed with impurities.
The team managed to discover this phenomenon through research and experiments for 7 years.
The research team hopes that this research will be useful for understanding spin interactions in metals and semiconductors and researching materials that have a rotating cloud phenomenon such as high-temperature superconductors.
The research team stated that they would carry out additional research on what phenomena are seen when adjusting the concentration of rotating clouds in pure metal.
The research results of the joint professor team were published in ‘Nature Physic’, one of the most prestigious international journals in the field of physics.
